To'alwhom t may concern,.- l

Beit known that I, WILHELM -HANsMANN, a citizen of the United States, residing aty Lastrup, in the county of Morrison and State of Minnesota, have invented certain new and useful Improvements in Traction-Drives for Looomotive'sgand I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled inthe art to which it appertains to make and use the same. V

IMy invention has for its object to provide animproved tractiondriving-gear for locomotives; and to the above ends the invention 'consists of the noveldevices and ycombinations of devices hereinafter described, and

. will be driven at the same peripheral speed.

The invention is illustrated in the'acoompanying drawings, wherein like charactersindicate likeparts throughout both views.

Referring to the draw' s, Figure 1 is-a plan view of the improved iving-gear with the" lbody vof the locomotive removed and away and Fig. 2 isfa vertical longitudinal section taken approximately on the line x2 w2- of Fig. 1 the body of the locomotive being, indicated in part by dotted lines.

v'The numeral 1 indicates the body of the locomotive. l A The numeral-2 in 'cates .the usual drivewheels that are secured on the axles 3, mounted in the usual -way in bearings on the frame (not shown) of the locomotive. These drive-wheels 2 are connected in the customr Tary way by links .4, and receive motion in the usual way through crank-rods 5. On the insecured bevel-gear 7 and a loose beve-geary r 8.. Each pair ofgears` 7 8 mesh with a bevel termediate portion of each axle-3 is 'a ri idly- .pinion 9 on the adjac'entends of shafts 10,`- which shafts extend in lopposite directions 'and are provided'at theirotherends with: ."bev'ehgears 1'1. i

" The minral g1g@ thesis of the `are thought to he desirable.`

4fore a locomotive is provided which .may be usedv on tractionengines vand tender, which wheels are secured on axles 15.' On each ofthe axles 15 and 13 is a'rigidlysecured bevehgear '16 and a loose bevel-gear 17. The gears 11 mesh with .thegears 16 and. 17 of the axles 13 andl that are nearest to the driving-axles 3. The gearsl and 17 also mesh with bevelears 18, that are connected in pairs by sha ts 19. v Y The shafts 10 and 19 are mounted in suitable bearings 10 and19, as shown in Fig. 2. Said bearings may be secured to the engine and ,tenderg but the drawings the upper portion of saidbearings are broken away.

The bearings for the shafts 10-19 are not shown in the drawings, but may be of an suitableform and may be attached to the locomotiveslrame in any suitable way. The. shaft 10, which transmits motion from the rear drivin uaxle 3 to the axles of the tender, is, provitle with a knuckle-joint 10a-and a longitudinal extensible section 10b, that is made un of telesooping angular sections,

`them-)by adapting the said shaft to'compen sate for movements of the tender with respect to the locomotive proper.

When the locomotive is moved forward, the different Wheels, axles, gears, and shafts will Vbe rotated in thearrows marked thereon in Fig. 1. The loosegears 8 and 17 are not necessary, but
